Are these asking prices or selling prices?
These are ADVERTISED asking prices (medians across tracked listings), not completed-sale prices. CarWhere does not yet have enough verified Terrain purchases to publish a reliable buyer-paid average — that figure comes only from real, verified deal sheets, never estimates.
Where does this data come from?
Market figures are derived aggregates (counts, medians, averages) computed monthly from licensed live-listing data covering U.S. dealer inventory. Buyer-paid figures come exclusively from verified buyer-submitted deal sheets. The two are never mixed.
Data sources, methodology & limitations
- Snapshot date: this page reflects the October 2026 national sweep. Figures refresh with one new snapshot per month.
- Asking prices: medians and counts are derived aggregates computed from licensed live-listing data covering U.S. dealer inventory (listings deduplicated per sweep). They are advertised prices — the out-the-door number a buyer negotiates is typically different.
- Buyer-paid figures: sourced exclusively from verified buyer-submitted deal sheets, labeled with model year and shown only when the sample is large enough. Asking data and paid data are never blended. No qualifying verified Terrain sample exists yet.
- Scope: national aggregates — local markets can sit meaningfully above or below these medians.
